Definitions

  • the present invention relates to oral care compositions and methods employing such compositions for use in treating or preventing calculus formation.
  • Dental plaque is a soft deposit which forms on the surfaces of teeth.
  • Dental plaque is generally believed to be formed as a byproduct of bacterial growth and comprises a dense microbial layer consisting of a mass of microorganisms embedded in a polysaccharide matrix. Plaque tenaciously adheres to the surfaces of teeth, especially along irregular and rough surfaces, and is typically found at the gingival margin, in cracks in the enamel, and on the surface of built-up dental calculus.
  • Gingivitis is the inflammation or infection of the gums and the alveolar bones that support the teeth. Gingivitis is generally believed to be caused by bacteria in the mouth (particularly the bacteria instigated in plaque formation) and the toxins formed as byproducts from the bacteria. Periodontitis is generally believed to occur where unremoved plaque hardens into calculus (tartar) which affects the periodontal ligaments. Periodontitis is a progressively worsened state of disease as compared to gingivitis. As plaque and calculus continue to build up, the gums begin to recede from the teeth and pockets form therebetween, which ultimately may result in destruction of the bone and periodontal ligament. These reactions lead to the destruction of the supporting structure, continued infection, and potentially the subsequent loss of teeth.
  • the plaque formed along the tooth surfaces thus provides a locus for calculus (tartar) formation.
  • Dental calculus, or tartar is a hard mineralized solid formed on the teeth when crystals of calcium phosphate are deposited in the pellicle and extracellular matrix of the dental plaque and become crystalline hydroxyapatite, sufficiently closely packed together for the aggregates to become resistant to deformation.
  • Regular brushing aids in preventing a rapid build-up of these deposits, but even regular brushing is not sufficient to remove all of the calculus deposits which adhere to the teeth.
  • HAP hydroxyapatite
  • an oral care composition that combats plaque by antibacterial activity and further controls and prevents calculus formation. It is difficult to predict the antiplaque efficacy of antibacterial compounds when incorporated in a delivery vehicle and particularly in oral compositions having other active ingredients, such as anticalculus (tartar control) agents. There is often a negative interaction between an antibacterial agent with other active ingredients or other components in a delivery vehicle of an oral care composition that reduces the effective performance of such oral compositions, including toothpaste and mouth rinses. This is especially true for many anticalculus systems.
  • a tartar control oral care composition which contains an antibacterial active compound from an extract of magnolia and an anticalculus system comprising tetrasodium pyrophosphate and sodium tripolyphosphate.
  • Active compounds extracted from magnolia include magnolol and honokiol which are antibacterial biphenol compounds. Tetrasodium pyrophosphate and sodium tripolyphosphate are anticalculus agents.
  • the present invention provides an oral care composition for treating or preventing calculus, which composition comprises an anticalculus agent and an antibacterial agent comprising a biphenol compound obtainable from Magnolia officinalis, wherein the composition is free of phosphate-containing anticalculus agents.
  • the present invention further provides an oral care composition for use in treating or preventing calculus and plaque, which composition comprises an anticalculus agent and an antibacterial agent comprising a biphenol compound obtainable from Magnolia officinalis; wherein the composition is free of phosphate-containing anticalculus agents.
  • the present invention provides a method of preventing inhibition of oral uptake of an antibacterial biphenol compound obtainable from Magnolia officinalis from an anticalculus oral care composition, which comprises formulating the oral care composition with the antibacterial biphenol compound and an anticalculus agent which is phosphate-free.
  • a phosphate-free anticalculus agent in the manufacture of an anticalculus oral care composition comprising an antibacterial biphenol compound obtainable from Magnolia officinalis, for preventing inhibition of uptake of the antibacterial biphenol compound.
  • the present invention provides a method for treating or preventing calculus formation in the oral cavity, which comprises contacting the oral cavity with an oral care composition comprising an anticalculus agent and an antibacterial agent comprising a biphenol compound obtainable from Magnolia officinalis, wherein the oral care composition is free of phosphate-containing anticalculus agents.
  • compositions which comprise an antibacterial biphenol compound obtainable from an extract of magnolia together with an anticalculus system comprising tetrasodium pyrophosphate and/or sodium tripolyphosphate
  • replacement of the phosphate-containing anticalculus agents with an anticalculus agent which is phosphate-free provides significantly improved delivery of the biphenol compound.
  • phosphate-containing anticalculus agents such as tetrasodium pyrophosphate and sodium tripolyphosphate appear to inhibit uptake of antibacterial biphenoyl compounds.
  • the oral care compositions of the present invention are free of phosphate-containing anticalculus agents, inhibition of oral uptake is prevented.
  • delivery of the antibacterial biphenol compounds is significantly improved thereby allowing increase in antiplaque activity of the oral composition or enabling a reduction in the amount of the antibacterial biphenol compound needed to achieve antiplaque activity.
  • the oral care compositions of the present invention are free of phosphate-containing anticalculus agents and in certain embodiments free of phosphates or polyphosphates, typically at least to the extent that delivery of the biphenol compound is reduced by no more than 20%, no more than 10%, or no more than 5% as compared with a control oral care composition containing no phosphate. Delivery of the biphenol compound is typically measured using a model system of delivery to saliva-coated hydroxyapatite discs, as described in further detail below.
  • phosphate denotes phosphates and polyphosphates including pyrophosphates.
  • Oral care compositions according to the invention must be free at least of tetrasodium pyrophosphate.
  • the antibacterial agent of the present invention comprises a biphenol compound obtainable, derived or developed from Magnolia officinalis, for example as an extract therefrom.
  • an "extract” of magnolia is an extract from dried cortex, or bark, of a plant from the Magnoliaceae family, such as Magnolia officinalis, (herein “magnolia”) or a synthetic or semi-synthetic equivalent of such an extract or an active component thereof.
  • the agent may be developed from Magnolia officinalis, such as a synthetic magnolol, honokiol, tetrahydromagnolol, tetrahydrohonokiol, propylmagnolol, propylhonokiol, isopropylmagnolol, isopropylhonokiol, butylmagnolol, or butylhonokiol which have demonstrated bactericidal properties against representative oral bacteria S. mutans, F. nucleatum, V. parvula, A. naslundii, P. gingivitis in the in vitro test Minimal Inhibitory Concentration (MIC).
  • MIC Minimal Inhibitory Concentration
  • the antibacterial ingredient in the active composition comprises one or more active compounds that have been isolated from an extract of magnolia.

  • extracting or “extraction” of a solid or liquid material means contacting the material with an appropriate material, such as a solvent to remove the substance(s) desired to be extracted from the material.
  • an extraction may be carried out by conventional means known to one of skill in the art, for example, by using an extraction apparatus, such as a Soxhlet apparatus, which retains the solid material in a holder and allows the solvent to flow through the material; or by blending the solvent and material together and then separating the liquid and solid phases or two immiscible liquid phases, such as by filtration or by settling and decanting.
  • the magnolia extract is isolated by supercritical fluid extraction (SFE) using carbon dioxide (C02).
  • the active antibacterial ingredient comprises either magnolol, honokiol, or both.
  • Magnolol and honokiol are non-ionic hydroxybiphenyl compounds, the structures of which are represented as follows:

  • the specific safe and effective amount of the compound will vary with such factors as the particular condition being treated, the physical condition of the subject, the nature of concurrent therapy (if any), the specific compound used, the specific dosage form, the carrier employed, and the desired dosage regimen.
  • the concentration the biphenol compound in the oral care composition will vary depending on delivery form, dosage regimen, end benefits, pathology, and/or the individual therapeutic requirements of the subject(s) to whom it is admitted depends upon the relative concentration of the active compounds in the extract, and as such, it is contemplated that the amount of biphenol compound present may vary as recognized by one of skill in the art.
  • the concentration of the active ingredients is typically dependent upon the form of the oral composition. For example, mouthrinses typically have a relatively low concentration of an active ingredient, as where dentifrices have a higher concentration to achieve the same delivered dosage based on ease of dispersion.
  • confectionary compositions typically have a relatively high concentration of active ingredient to enable sufficient dispersion as they dissolve or are masticated.
